Solvent Extractor (Dean Stark)



With this device, the saturation is measured by a process of distillation extraction. The process uses Dean-Stark a flask with a hydrocarbon solvent (toluene), a heating element, a condenser and a graduated receiver. Solvent (toluene) is heated to its boiling point (110°C) and the vapors move upwards evolving the rock sample. Toluene begins to extract the oil and water present in the rock. Based on the simple calculation, the saturation of water, oil and gas will be determined within a core sample.
